Cramped spaces, less water, and poorer living conditions are all symptoms of urbanization. Higher living costs also promote poverty and classism within cities. Despite this, many people long to take advantage of job opportunities, cultural experiences, and the hustle and bustle of city life.
While urbanization has existed as long as humanity, the Industrial Revolution sped this process greatly. For one of the first times ever, farming was no longer the primary source of income for the common man. Factories began opening within cities, and soon people were flocking to the area. This article by Forbes magazine discusses how more and more people have begun living in cities in modern time, greatly affecting the infrastructure of each city: http://www.forbes.com/sites/danielrunde/2015/02/24/urbanization-development-opportunity/ .
This is rooted in industrialization, as the Revolution shifted the focus from suburban areas of income to urban areas of wealth. This also shows its industrialization roots in the continuous problems of infrastructure, also highlighted in The Conditions of the Working Class in England in 1844 by Freidrick Engels. This booked describes the problems of an overflowing population and the problems of a lagging infrastructure.http://webs.bcp.org/sites/vcleary/ModernWorldHistoryTextbook/IndustrialRevolution/PSEnglesManchester.html
